How to remove gaps when adding multiple clips at once
Thanks VK In retrospect, I think I should have recommended: Do not rely on Vegas to set the project properties to match the source for you, but first make sure that the default project frame rate is the same as your clips (use say Mediainfo if you are not sure of the source frame rate) before you drag them to the timeline. It is OK to accept Vegas's offer to do the matching if only the frame sizes are different. Another strategy may be to drag the first clip to the timeline, let Vegas set the frame size and frame rate, and then drag the remaining clips to the timeline, being sure not to leave a gap at the end of the first clip.

How to remove gaps when adding multiple clips at once
Thanks for the responses in this thread which led me to the solution to my problem. I have been a long-time user of Vegas but recently started getting problems of gaps of about 1 frame between many but not all clips when I dragged them to the timeline. I spent hours looking for the cause. It turned out to be due to the default project properties of Vegas being set to an NTSC template (29.970 or 59.940 fps) when the source clips were to a PAL template (25 or 50 fps). Vegas asked me if I wanted to match the project properties to my source, which it did, but apparently after it had put them on the timeline. A PAL clip will almost never be a multiple of an NTSC frame in length, hence the gap at the end. The solution is to not rely solely on Vegas to set the project properties to match the source for you, but to first make sure that the default project properties use the same video standard as your clips, before you drag them to the timeline.

Vegas Pro 18 -- audio gap between file segments
If you want a GUI program to concatenate (link together in a chain) a series of files regardless of content, then try the free Igorware File Joiner. https://www.igorware.com/file-joiner If you have a Sony camera, you can use Play Memories Home to transfer and automatically join AVCHD files that have been split into 2 GB chunks (or less for the last one) because of the limitations of the file system used on SD cards. Panasonic cameras split long AVCHD recordings into 4 GB or less chunks, but their corresponding program HD Writer does not join them, so you will have to concatenate them yourself. If your camera records a long recording session as a series of MP4 files, you will probably find that simple concatenation is inappropriate. You should therefore use Vegas or some other video aware software to join them.

What is the best way to reduce shimmering video noise?
Of course! I had a mind-set against resampling because there would be some loss in video quality, but there is also loss in quality when downsizing to 720p, which I had also originally rejected for the same reason. I hadn't thought of directly comparing the two. I could also look at using Twixtor (which I have) for the conversion. The subject matter generally has simple motion suited to its algorithm, but I might have to do the conversion at 1080p not 2160p. Thanks for the suggestion and your presentation! Could I prevail upon you for your opinion of 2160p25 to 1080i50 (25 fps interlaced, with clip properties set to "disable resample" during render)?

What is the best way to reduce shimmering video noise?
At 1280x720, DVD Architect (and probably my BD player too) only supports 60p, 50p, 24p and 23.8976p, so 720p25 is not an option. What do you mean by 1080p25/p24? Slow down my 25 fps to 24? If so, I would either get a small drop in pitch or I would have to use elastique time-stretch or similar, which may noticeably affect the music quality for people with better ears than what mine are now.

What is the best way to reduce shimmering video noise?
I am prepared to re-sync the sound for each item or bracket separately, if necessary. We will see. Neat Video is not cheap but looks good and is affordable, so I will look into that. I did a test comparison on my TV of 1280x720-50p AVC 16 Mbps versus 1920x1080-50i AVC 16 Mbps, both rendered with disable resample on the clip properties. When viewed from a distance, they both looked much the same to my ancient eyes with cataracts developing, but the 1080-50i looked slightly washed-out compared to the 720-50p. When viewed close up, both looked grossly over-sharpened, but the greater blur on the 720-50p softened it somewhat. I saw no evidence of deinterlace artifacts on the 1080-50i. In view of the above and the fact that my zooming won't appear so bad with 720-50p, I will probably go with it. Thanks everyone for your thoughts and advice.

What is the best way to reduce shimmering video noise?
I also recorded with two microphones best placed for the choir. As I already said, my clip showing the full scene uses the sound from the camera, while the blow-up of the compere uses the sound from the close microphones. In retrospect I could have had another microphone near the compere, because my recorder takes up to 8 simultaneous channels, but I didn't. If you look at the full scene, you will see the left microphone appearing to be above the pianist's head and the right microphone appearing to be above the head of the lady second from left. The mics are actually placed at the quarter and three-quarter points of the breadth of the choir, and sufficiently distant from the choir to not have the front row dominate. I have recorded the audio and made CDs for many years and have found this to give good separation and to work well. It is not always optimum for the guest artists because I never know in advance where they are going to stand. The CDs only have music, no compere's comments. BTW, you did notice the emoticon in my post? My statement was meant to be tongue in cheek - I have to weigh up pros and cons of several alternatives and what might be generally best for the few viewers of the final work. My guess is that most people will only have a DVD player, and in that case the blur of the highly zoomed compere won't be noticeable at all. Some people may only be interested in just a video file, which can be almost any resolution. But I also want a high-resolution Blu-ray version for myself at least, because I like menus to find items quickly. I remember years ago I had an audio peripheral, which had an ipod socket, connected to my then 50-inch TV set. A young friend noticed it and connected his portable player to it. All his movies had low resolution suitable for a small portable device. I thought his movies looked terrible when shown on a big screen, but he was over the moon!

"Then Peter Duke should put some more effort in his project while recording instead of trying to correct his amateurish recordings afterwards in post..." I never saw myself as anything but an amateur. This is my first attempt to see what I could do with one unattended fixed camera while I was singing in the choir. A manually set low ISO value is one thing I could look at. Any other advice?

Hmmm, it looks like the wrong pair of fields are getting associated to form a frame. I need time to explore further, including 720p.

What is the best way to reduce shimmering video noise?
fr0sty I think what I should do is first render my 25p UHD project to 50p 1920x1080 HD, with the clip properties set to "disable resample". The output file will then have duplicated frames in order to double the frame rate. If the clip properties are set to "smart resample" or "force resample", the additional frames will be interpolated or merged versions of the two frames either side of the new frame, which I don't want. Now, when I render the 50p video to 50i, each field will pick up the appropriate line and I won't lose vertical resolution. I will now try to verify all that.

What is the best way to reduce shimmering video noise?
I chose the zoom value of 5.5 or whatever it is to exclude all members of the choir to our left of the compere. I thought that preferable to the increased artifacts of zooming. The compere is only of secondary importance to the choir, so lowering the resolution of my final video to give uniform resolution throughout seems like a waste. Feel free to differ with me on that point, of course. If a TV news broadcast shows old SD footage during a HD transmission, they don't drop the whole news session back to SD to keep the appearance uniform.

What is the best way to reduce shimmering video noise?
Regarding choice of BD format, I see no reason to go from my 25p source to 24p with the consequential audio pitch change if no frame changes are made, or the consequential video degradation if frames are interpolated or dropped. There is no 1920x1080-25p option in Vegas, but there is a 1920x1080-50i option, which I have chosen. With smart resample, Vegas merely makes the second field in the frame the same as the first. You can see this by loading the 50i video into Vegas, setting the project properties to 50p, and then stepping along one frame at a time. With true 50i video you will see 50 distinct frames per second, but with 25p source you will see 25 pairs of distinct frames per second, where the two frames in the pair are identical. How TVs display interlaced video on a progressive screen and what deinterlacing they do is a mystery to me, but I think I am on pretty safe ground in assuming that my 50i it will look the same as if it had been 25p.

I have uploaded to dropbox an excerpt from the original video file and a zoomed version as it will appear in the final Blu-ray. https://www.dropbox.com/sh/wkx9vvrkt0vvx1h/AAB9XlPIExxnzYpKOkt2pxtHa?dl=0 The sound in the original excerpt is as recorded by the camera while the sound in the final excerpt is from the two microphones near the choir. You will notice in the zoomed final version that the panelling behind the compere is shimmering. What can I do to reduce this shimmering? The performance is gone, never to be repeated. I know I can’t make a silk purse out of a sow’s ear, but what I want is the most presentable sow’s ear that I can get. In front of the compere, you will see six trophy cups awarded to the choir many years ago (long before television and my time in the choir!) when choral competitions were in vogue. I was not in the performance because of a persistent cough and croaky voice.

Converting 50p to 59.94p (60p) using Vegas and Twixtor
I found a problem with Twixtor. It does not generate the correct number of frames according to the rate parameter. For instance, a 50p video with 28757 frames and a rate of 83.417% (for 59.94p output) should give 34474 frames (to the nearest whole frame). Instead it produces 6 more frames. I tried experimenting with the rate parameter, but the output number of frames varied in unpredictable steps. Unfortunately the point that I was looking for had an exceptionally high step. Rate values from 83.436% to 83.447% gave 34476 frames but 83.448% gave 34464. I have referred the problem to the makers, but no reply yet. I had a look at DaVinci Resolve and got an error when trying to run it. A web search revealed some posts that suggested that I might need new graphics drivers, un update to OpenCL or a new graphics card with required capabilities. I have enough trouble with Windows 10 updates to spend time on researching that for the moment. I don't fancy throwing away half my frames to convert my video, so I rule out that approach. I don't appreciate the so-called "film" look over the so-called "soap opera" look. I suppose that is because I was never a film buff. That leaves AVISynth. People are still playing with that (e.g. FrameRateConverter by MysteryX) and building on the work of John Meyer and other giants. I will go down this path if I can't force Twixtor into submission. Thanks to those who have replied

where can i find pro-level editing tutorial
There are two aspects of good video editing to consider: being creative and using the tools on hand to implement that creation. This forum is mainly about the latter. If it's the former you are interested in then you should look eleswhere. Personally, I weary of the modern wizz-bang presentations I see on TV, particularly in commercials with lots of primary colours, especially red, and the lettering jumping out at you. Moving bizarre backgrounds should be banned. Pop concerts seem to be more about visual effects than sound. It is all aimed at over stimulation. Please don't go down that path. Is there a connection between such presentations and mental disorders?

part of my audio didn't appear
Video usually has some background noise. Was there absolute silence at that point and only that point? Can you graft the "wat" back into the audio, using Vegas or an audio editor? The latter would involve demux and remux of audio and video. If not, do it all again and don't delete your project before you check your work thoroughly. Project files are small and worth saving until you are absolutely sure that you will never need them again. As to why it happened, is like asking how long is a piece of string. It shouldn't have happened and doesn't normally happen, so the cause must be obscure (one of very many unlikely events). Don't overlook a possible editing mistake on your part.

M2TS and MTS
The odd thing is that I have 2 other friends who use the same make and model camera as the one I am having trouble with and there is no problem incorporating the output of these 2 friends into my projects. Post Mediainfo and other data as requested by Nick.

M2TS and MTS
The BDAV spec includes both HDV and AVCHD. HDV usually has a M2T extension which is standard MPEG2 transport stream, ie. missing the extra bytes in each packet, and implies MPEG2 video. MTS and m2ts imply MPEG4.

M2TS and MTS
MTS and m2ts are the same thing, namely MPEG2 transport stream container modified with the addition of of extra 4 bytes in each packet to improve playback. It was created for Blu-ray Discs and later adopted for AVCHD but because the latter used a file system that only supported 8.3 character file names all upper case, m2ts was renamed to MTS (as well as other cosmetic changes to file names). AVCHD file lengths are limited to 2GB for Sony or 4 GB for Panasonic because of the file system, so longer scenes are split into chunks in the camera that need to be concatenated back into a single file before use in video editors. Failure to do so will result in usually a two frame loss in the video and a longer loss in the audio at the join. The reported problem must be due to the underlying video coder, not MTS itself.
