Red screen at the end of each clip?

MyUsernameIsMyName wrote on 5/30/2021, 7:33 PM

Hello ya'll, I've encountered this problem for each clip on my timeline. At the end of each clip, there is a red screen for like a millisecond. I don't know what the problem is. I've tried to search it up but is having a hard time. What I do is import my media, select all of my media and create video proxy for all of it, I then put it all on my timeline and disable resample on all my video. I don't do any crazy editing or add anything else. Still new to editing in 4k 30fps.

 

 

Edit: Clips are from iPhone 11 Pro. Transfer files from iPhone via SimpleTransfer MOV. Using Vegas Pro 18 edit.

Are these clips from a camera? If so it's probably corruption for a frame or two as the camera ceases recording or writing the file. How are you transferring/capturing the files from your camera to your pc?

@MyUsernameIsMyName - Do your Project Settings Match your Media? Does your Timeline Scale Match your Media? Should there be a “;” separator instead of the “:” for Frames?

Yeah these clips are recorded from my iPhone 11 Pro. I usually transfer the files via "SimpleTransfer".

Transcode your video and see if it still exists.

Yes my project settings matches my media. I click on "file" then "new" and then click on "match media video settings" and click on "adjust source media to better match project or render settings" box.

I believe my "Timeline Scale Match Your Media", how do I find out?

 

How do I find a ";" sperator instead of the "." for Frames?

@MyUsernameIsMyName - And has this “Simple Transfer” been successful before now?

Yes it has been successful before now. Any other program I should try when transferring files via iPhone?

@MyUsernameIsMyName - Uh-huh... What has been your Workflow from iPhone to PC and then to VP?

Fairly simple, use Simpletransfer to get my video file MOV onto my folder. Start a new file to match my video setting and then import the file on Vegas Pro and create a video proxy. Load all my video file onto the timeline and then desample all the clips. I then review all my clips and notice the red screen at the end of each clip.

You will need to trim the offending frame(s) from the end of each clip. Maybe someone can help you with a script to do it in bulk or quickly and easily.

Yeah, it’s a pain when you have multiples clips haha.

Not if you use a script. You can select them all and then the script can trim on or two frames off the end as needed for all selected events.

How would I do that?

If that's really the problem and you want to trim frames from each selected event, here's a free tool that will work for you.

@MyUsernameIsMyName

Although the Trim Frames tool "works", I doubt if it will solve your problem. I suspect that the real issue is that since phone footage is variable frame rate, it almost always end at a position on the timeline which is not a frame boundary. To test for this, open Internal Preferences and Show only.... "quantize". Set the two results, "Show unquantized event start and end" to True.

If not quantized, you will see a red bar and the beginning or end of the event. Here's an example, from some iPhone11 HEVC 60P footage showing that the end of the event does not fall on a frame boundary.

I have set the loop to indicate the start and end of the frame. Setting Vegas to Quantize to Frames does not solve this problem for variable frame rate footage. Nor will trimming frames. To actually change the event length to correspond to an actual frame boundary, you should use another tool. Quantize to Frames.

After running the tool, the timeline looks like this with the end of the event falling precisely on the frame boundary and you will note that the red bar disappears.

While transcoding "works" since it converts your footage to constant frame rate, it will also lead to a reduction in quality due to the re-rendering.

@MyUsernameIsMyName If your system struggles with the Variable frame rate, though I see you use proxies, converting will ease the load on your PC. The util, VFR2CFR, link via my signature, can be used to convert to CFR.
