When importing AVCHD files from different recording sessions but part of a same project when .MTS files are dragged into a timeline and multiple timelines from different recording sessions are open at the same time...audio playback from other .MTS files in other timelines occur. This most likely happens because every .MTS is labelled with a generic number 00001.MTS. It could possibly be that Adobe Premiere has the ability to catalogue and continuously keep things organized...but when it sees multiple files with the same numbering system it's not hard to imagine it getting confused even thought the clips are in separate BINS and were imported at different times. Maybe a solution is to have a date and time put before the generic number so each .MTS file is unique by filename and this will never happen. I have been lucky enough to save the project and reopen and the timeline plays back properly...but the unpredictable nature of the .MTS file naming problem is unnerving...especially when you have invested a week editing. The main problem is the way MAC OSX sees the AVCHD as a package that you can't "expand" to see the contents. Otherwise renaming and reconnecting files might be a "FIX" but the import process needs to be improved because of the way MAC OSX sees these files when imported. Premiere needs to make unique names when imported.

For years, I've had issues with the sequence timecode matching up with the burn-in timecode of my videos. It's gotten worse in version 14.8 and 14.9.

When I would load in a H.264 mp4 or mov files and create a new sequence from clip, the sequence timecode would always be 1 frame off. I have been transcoding it to ProRes 422 (in Premiere) and creating a new sequence from that clip --and then timecodes would match.

But in 14.8 and 14.9, it's much worse and the timecodes are way off. I have gone back and forth with 14.7 and can confirm this.

After messing around, I noticed that when I go to Interpret Footage, it shows my video being 29.9701 instead of 29.97. If I modify it to assume frame rate 29.97, then the timecodes will match. Even so, it seems like a bug that's been around for a long time, but worse in 14.8 and 14.9.

I've recently been encountering strange issues when Importing .MOV files into Premiere 2019 or 2020, where I'd get a "File Import Failure: We were unable to open the file on disk" error. The error also occurs in After Effects, with the same files.

The files import or open without issues in every other video application I tried (DaVinci Resolve, Quicktime Player, Screen (Videovillage.co), VLC, IINA, Telestream Switch Pro & FCP-X).

After a bit of sleuthing, I figured out that the problem only occurs with .MOV files that were specifically transcoded out of Apple Compressor 4.4.8 (which is the latest version for macOS Mojave, as of 2020-10-17), AND also contains audio tracks.

MOV files that were encoded as "Video Only" out of Compressor 4.4.8 did not exhibit the import issue. Nor did the same file transcoded out of Compressor 4.3.2 (last High Sierra compatible version) with audio tracks enabled.

.MOV files transcoded out of other apps (such as EditReady) did not have any issues importing.

Changing the video/audio codecs or encoding parameters used to transcode them did not have any effect on resolving the issue.

Files that were transcoded to non-MOV containers out of Compressor 4.4.8 (e.g. .MXF & .M4V) all import fine, regardless of the presence of audio tracks in the transcode.

Deleting the physical audio tracks from the suspect .MOV files (using Digital Rebellion's "QT Edit" tool) did enable them to be imported without error. But obviously, this isn't a particularly ideal workaround if your camera footage has sync'ed audio in it.

So there seems to be some sort of bug that is causing File Import failures with .MOV files that were specifically encoded with Compressor 4.4.8 .mov files, AND also contains audio tracks in them.

I was first inclined to submit this issue to Apple as a bug, but the fact that no other application on my Mac (macOS 10.14.6, with latest Apple "Pro Video Codecs" package installed) seems to have problems importing the same files makes me think it's an Adobe specific bug.

Here are my test files, if anyone wants to help investigate:

Master ProRes .mov file (this is the source master file I used for my testing): https://d.pr/v/k6DYrJ

Test Transcodes: https://d.pr/f/MGIgWv

The Test transcodes in the .zip file contain the transcodes of the Master ProRes file, in various formats, from Compressor 4.3.2, Compressor 4.4.8 and EditReady 2.6.5. All the Compressor 4.3.2 & EditReady encodes import into Premiere/AE without issue. The only encodes in the Compressor 4.4.8 folder that import fine are the .MXF and .M4V files, as well as the .MOV file which was encoded with the "Format" option set to "Video" instead of "Video and Audio"

My current workaround is to "rewrap" (NOT re-transcode) the offending files to new .MOV files, using EditReady. This appears to strip out whatever internal inconsistencies existed in the original transcode, and allows them to be imported into Premiere again.

Here's a link to an EditReady-rewrapped version of the "compressor4.4.8-Apple ProRes 422 LT.mov" file. This imports into Premiere without issues, and is not re-transcoded, either.

Media Browser is awful - to the point that I spent $300 on Davinci Resolve JUST to get a working media browser. I capture clips at 400Mbps which results in very large files. When editing I only want to capture the good takes from SD to my storage drive. So I need to view them. But Media Browser refreshes every second, which means I lose my place and have to scroll down over and over and over. At some point Media Browser will refresh before I get back to where I was. Also, the clip preview performance is very sluggish. So I bought Resolve - which for me is essentially a $300 media browser that only refreshes the folder I'm viewing when I tell it to, plays clips smoothly, and shows them in a window that's large enough to evaluate the video.

Hello, It would be great if there was a way to link folders on a computer or hard drive to bins in Premiere. That way, if I copied a photo or video clip into my folder on my hard drive labeled "Day 1_Footage" (for example) then it would be great if (assuming I already imported that folder from my hard drive into my Premiere project window as a new bin) that footage or photo automatically imported into that given bin. If I add a new photo into my hard drive folder titled "Photos" then it would automatically update the bin in Premiere also labeled "Photos" as long as I specify ahead of time that I want them linked. This would save time if we didn't have to manually import all assets after we already placed them in our specified hard drive folders.
Thank you.

At our TV station We have several Windows 10 editing systems and they recently updated to the new premiere V15 release and now our old collection of thousands of HDV MPEG-TS files from Sony HVR-Z1U cameras no longer work in premiere. They Import and just show the "media pending" picture until you click on one and try to navigate it and then the error log says:

"Frame substitution recursion attempt aborting after multiple attempts on file"

This happens on every machine that was updated.
This happens in premiere, after effects and media encoder
This does not happen in the previous version 14, i have a laptop that didnt update and those files work fine.
I am in the Premiere Beta test program for closed captioning, the Current Beta version still works fine with all these files.

here is the media info for an example file:
