How old is this i7? This Radeon is from 2011.

I wouldn't expect good performance from a system of this age, especially when multiple clips are playing at the same time. You can right-click on media and "create video proxy" to improve playback or select a tough part of the timeline to playback and hit shift-b to create a temporary preview.

Don't expect good performance if you refuse to meet the minimum system requirements for the operating system and you are using 11 year old hardware. As mentioned above, proxies may help.

I noticed I was using 1080p50fps AVC, instead of the 30fps poster was using. Changed project to 30fps, with 30fps media, played it though a few times and did not have any problem with default setting.

However you can still try Legacy AVC if aren't using it now to see how it goes. I don't recall VP16 or how to use Legacy AVC, I don't think it was even called that back then.

 I don't recall VP16 or how to use Legacy AVC, I don't think it was even called that back then.

VP16 didn't have either Deprecated Features or File I/O tabs under Options/Preferences, but Legacy AVC can be selected in the Internal settings menu. To get to Internal in VP16, click on Options and then Shift-click Preferences - this will add the Internal menu to the tabs:

In the filter field at the bottom of Internal, type in 'legacy' and the top item that will display will be 'Enable Legacy (Mainconcept AVC / ...). Change FALSE to TRUE, hit Apply and OK. It would be great if you could get back to this post to let us know of this improves timeline performance or not.

Thank you @Dexcon ......I tried it and no it didnt make a difference.

@fr0sty .... its called doing all I can. After my brain cancer in 2011-2012 and a fixed income I do what I can and with what I have to do it with.....That machine works just fine for the music audio editing I mainly use it for, I just like to mess with and try to do video. I definitely dont refuse.....I cant

@RogerS Thank you Roger, I was kinda off when I listed config. trying to go off memory (which between the brain cancer and getting old (60)....is not too good HAHAHA. I looked up my service tag on dell and its:
AMD Radeon HD 7870 2GB DDR5
3rd Gen Intel Core i7-3770 pro cessor 3.40 GHz with Turbo Boost 2.0 up to 3.90 GHz
32GB Dual Channel DDR3 1600MHz

thanks again, and I'll just keep pluggin along the best I can.

@brent  ... one thing that we don't yet know is the source of your video? Is it a phone camera? If yes, phone cameras typically record in Variable Frame Rate (VFR) rather than Constant Frame Rate (CFR) that is typically used by 'handicam' cameras. Unfortunately, Vegas Pro doesn't deal all that well with VFR video in many cases. if your video is VFR camera phone video, the usual suggestion over the years has been to first convert the VFR video to CFR via a transcode utility such as the free HandBrake utility - https://handbrake.fr/

Otherwise, it would be helpful if you were to post a detailed MediaInfo report of your video media using the free Mediainfo utility. More info here: https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

@Former user  ... From your uploaded pics, I see that the 'table cloth' was well and truly set for those shots. My wife and I had a perfect sunny breeze-free day at the top of Table Mountain when we were there some 8 years ago, but the amazing 'table cloth' appeared during the afternoon, spilling over the mountain's edge like a super slow motion waterfall.

I used up to Vegas Pro 15 with a very similar system from 2011- it was slow as I had to create proxies for all 4K footage (right-click on media and "create video proxy" in Vegas) but it worked. If the hard drive is a regular spinning one consider replacing it with a faster SSD.

Beyond that what Dexcon says is important- Vegas performs better with some media than others. Handbrake can batch convert troublesome files into ones that will play as well as your system can handle.

Good luck!

@Dexcon Here is one clip. It was a .mov and I was having trouble and converted it to an mp4 which made it easier and worked better. And to answer your question, yes The guys sent me thier footage from a phone vid. Mine was also done from an iphone , 4k-60fps

Your third generation Intel is the big elephant in the room; if you are unable to upgrade, like many of us, the aforementioned proxies to XDCAM-EX are a partial solution, but even those may not hold up with timeline effects or generated media.

Thank you @brent for uploading that Mediainfo report. I'll leave it to other better informed forum members than myself on the following point, but the frame rate is 59.94 fps which has been commented on over the years on the forum as sometimes causing timeline playback problems. Perhaps this is the cause of the slow timeline performance. If it is, then transcoding to 29.97 or 30 fps would probably help. I'm more than happy to be corrected on this as I am in a 25 / 50 fps area.

@Dexcon Is iskysoft video converter do the samething that Handbrake does?

Unless it's intended for slow motion when you do the conversion try converting to 29.97fps and then editing and rendering at 29.97fps in Vegas. It should help with performance.

I've never used iskysoft but Handbrake and Shutter Encoder are free tools many of us are familiar with and can give guidance on for best settings.

... Is iskysoft video converter do the samething that Handbrake does?

I've not used that utility so I don't know, But give it a try a see if it can transcode 59.94 to 29.97 / 30 fps.

@RogerS @Dexcon Thank you , that will give me something to work on today. I did manage to get this done by scrubbing along and editing what I could, just playing at it waiting for a friend to come do her vocal track and video for this:

That looks and sounds great! For multicam I'd highly recommend proxies on all the video files and all should work reasonably well.

@RogerS Thank you sir! I can produce the music, this was my first try at trying to be serious on a video....

@brent not a bad first try!

Thanks @Reyfox .....just waiting on her to replace vocals on recording and for her video to finish it....

@RogerS @Dexcon , Man that really helped! transcoded all clips to MP4 HD 1080P an 29.97fps and that really helped alot, as well as the vid proxy. And as you said I looked and my 4k 60fps guitar vid was VFR....now everything is 30 fps constant. Thank you all for your help!!!

Don't expect good performance if you refuse to meet the minimum system requirements for the operating system and you are using 11 year old hardware. As mentioned above, proxies may help.

I'm not talking about your hardware, I'm talking about not being willing to upgrade to Windows 10 (which can be done for free, here's how), VEGAS requires certain things in Windows 10 to function properly.

VEGAS should still function ok on older hardware, just slower, maybe with a few more crashes. As long as you keep it to 1080p editing, you should be fine on your setup, but Windows 10 is important for it to be able to do all it needs to do.

If you have problems after upgrading to Windows 10 (as you mentioned before), check back here and we'll see if we can help you sort them out.
