Media Offline on a few frames ruins the rest of the clip

PostMon Jul 12, 2021 5:33 pm

Hello all,

I have been using Davinci for a few years, but I'm just a basic user. I'm currently running Davinci 16 on an NVIDIA GeForce RTX 2060.

The issue I have is that if there is even one second of corrupted video, Davinci can't seem to handle it and the rest of the clip in the Timeline is useless. Once when this happened it wouldn't load the rest of the audio, the next time the rest of the video was pixelly and corrupted.

My current workaround is to open it in Windows Photos, edit out the flawed second, then save as a new file. Then when loaded into Davinci, the entire clip is perfectly fine.

Why is Davinci so sensitive that it can't recover from one second of flawed frames? Is there a setting I can adjust to make it less sensitive/more resilient? I'm using the free version, not Studio.

Thank you very much!

What specific format is the bad file? If it's highly-compressed material like H.264 or H.265, a second or two of corruption could present problems to any playback software.

I just checked - yes, it is 264. There doesn't seem to be another option when filming on a Canon camera to an SD card.

Shannon, I too use a Canon (a G40) shooting h264 in an mp4 container. I've never had a problem with corrupt frames at the start of a shot even when shooting at 50fps. You shouldn't be getting corrupt video so is the SD card you are using starting to fail and in need of replacement? These are the SD cards I use.

Thank you for the picture - I use the very same cards except in 128GB. That is reassuring that I picked the right brand an type of SD card.

I suspect that one specific SD card is causing me problems, so I have marked the outside to be used only in emergencies. Then I'll see if the problem continues.

I'm just surprised, overall, that Davinci isn't more resilient in these situations. That it doesn't recognize when the flawed frames have completed, then process the rest as normal. :(

Thank you for your help!

Davinci is resilient ... but you may not be happy with the outcome ...

Under Preferences: User Tab: UI: Last choice is Stop renders if frame or clip cannot be processed.

It is checked by default ... uncheck it and Davinci will place a Media Offline flag at every point where you
had a bad frame .... if it is a card read error or corrupt frames your clips will be littered with these ... leaving you with a huge mess finding and trimming them out ...

It will however give you an indication of at which points the bad frames occur.

Thank you for the suggestion, I will try it and see. I don't imagine I'll be overwhelmed as the last to occurrences example had only a single flawed spot.

That's why I prefer this. Better internal recording formats.
