HEVC importing issue

Hi everyone, I recently discovered an issue while editing funeral livestreaming videos created within Livestream Studio 6.

If Studio 6 has HEVC enabled, the video is drastically elongated to approximately double its duration.

See the jpg attached.

Unlinking the audio and video tracks and reducing the video length doesnt come close to marrying up the timing between audio and video.

I have tried several conversions but am at a loss to find an accurate method of repair.

System info attached.

Try using Shutter Encoder (donationware) to convert a clip prior to importing it into Premiere Pro.  Based on what you've described, I would try transcoding your HEVC original files to ProRes 422 LT.

    Thanks Warren, just wondering how large the ProRes file would be if the original is 14.1Gb?

    1080p24 to 1080p30 ProRes 422 LT will be about 700GB per minute.  I usually round up and allow for 1GB per minute.  So, an hour will require about 60GB.  The sustained data transfer rate isn't too high, so a standard high capcity hard drive should be find for media storage.

    The Apple ProRes White Paper has an appendix that breaks down data rates and stroage requirements for ProRes at different frame sizes and frame rates.

    Does this occur with similar media or only with the media from this specific software? Try a trial of different software to see if it might give you a better result.

     

    Thanks,

    Thanks Kevin, but that is the software we use, and it's only an issue with HEVC recording. h.264 recording has zero issues.

    <<but that is the software we use>>

    Can you post a link to the the message you left on the forum for the 'software you use' letting them know of the problem with their HEVC format.
