When you are "seeking," (which means QUICKLY looking through a long video by clicking and dragging the playhead with the cursor,) there is sometimes very high "prefetch latency," meaning that frames will load slowly, resulting in very few frames being shown. This can make it very difficult to find what you're looking for.

But when seeking, perfect frame accuracy is not nearly as important as seeing what you're doing. Therefore, to reduce the "prefetch latency," I suggest that the nearest I-frame is loaded and displayed FIRST, (because I-frames are always the fastest to load) while the exact B or P frame is still being slowly decoded. As soon as it's decoded, it can be displayed, replacing the displayed I-frame.

If the user is seeking quickly, there might not be enough time to load the P and B frames before the user has already moved the playhead nearer to another I-frame. This is fine! The I-frames should always take priority.

In VLC, there is a similar feature called "fast seek."

Combined with my "ghost playhead" feature suggestion, it would be made clear to the user exactly what is going on. (Linked below)

However, it would probably be important for fast seeking to be optional, and perhaps even off by default, as it may confuse some users.

NOTE: This works best if only ONE video source is visible. With more than one video on the timeline, the I-frames will probably not be in the same spots. Nevertheless, it COULD still work, but there would have to be multiple ghost playheads. This might be too difficult to code, and confusing and frustrating for users, who won't understand why premiere is showing video frames out of lockstep, especially in cases where one video has high prefetch latency, and the other is low.

Hi!
I've heard I am not the only one to have this issue. Preview window in Premiere Pro 22.0 is terribly tearing. Like some kind of V-sync bug. It's not there on ver. 15.1.0. Though it's still has bugs.
I have read everything. I turned on/off/what ever else V-sync in my Nvidia control panel for Premiere. Turned on/off GPU for previews in proj settings. Forced the system to use different video adapters for Premiere. Nothing. Tearing. Even on pre-rendered clips. Even without any effects applied. On Full resolution, "High quality" preview settings. No matter if it's Low-res HD footage or heavy 4K vids.
If I open the same preview file from Adobe previews folder it runs OK. Exported video is OK. But it terrible to work. I can't say, if footage is OK, until I export it. And I normally add some glitches to my video transitions. How do I know, is it my glitch or a bug?
Definitely needs to be fixed. Check out attached file for an example please.

BR, Anton.

There are cases in news broadcasting where you can not make it in time for your news piece to air and you have to broadcast live from your timeline via SDI for example. In this case it would be helpful to have an option or a button to help make Premiere ready for that so when you know you are going to broadcast live from your Premiere timeline you can just press that button and it automatically suppresses every action that could interfere with your broadcast, for example auto-saving. This would help with the pressure of situations like this and we have this case regularly.

I've been using this new version of Premiere Pro for a couple of days and it seems to have a lot of bugs, at least on my computer. I already reinstalled, cleared the preferences, installed an older version and even so the software crashes and simply don't play the preview video. The button stucks and won't play the timeline, I can save the project when that happens, but every time I'm working on some project, old or new, after 20/30 minutes the playback stucks.
I'm also having this problem on the export options, and when rendering on Media Enconder 2022, sometimes it crashes after 90% of the render. Please help us! I'm not the only one with this problem.
I'm on a brand new computer, the system details are below:

• Dell Latitude 5420
• Windows 10 Enterprise
• 11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz 1.80 GHz
• 16Gb RAM
• 64 bits operational system
• Video adapters: Intel Iris Xe Graphics 27.20.100.9749

Footage from the Sony FX3 is having playback issues with Premiere. The odd thing is it plays back normal at full regulation, but if you change playback to 1/2, 1/4, or 1/8 it's super choppy and doesn't play back right.

The footage is recorded in XAVC S-I which is at h2.64 intraframe codec so it should work fine for editing.

The issue is happening in the most recent version of Premiere on both our iMac (intel processer) and our PC workstations. The footage is stored on our shared NAS, with 10gig ethernet.

I am using preview files (render in to out) to get better playback, and I use high quality prores 422 as my preview format in the sequence settings so I can render previews eventually in the output settings and save time. this works great but one annoying thing - I am working with high resolution, and I set my playback resolution to 1/4 or even 1/8 to get smooth playback and it works, but when it reaches the rendered preview section in the timeline - it's always high quality... meaning I get a jump in resolution, and the playback is still choppy (it's trying to playback high res 422). the playback resolution should force the preview to play at that resolution, seems like an oversight. please address this.

thanks

On Windows 10 PP2021, any video file would stutter in playback.

Seems to have been due to a mis-configuration between the microphone input capability on my system and the configured of audio sample rate and bit depth on the mic input.

Originally, on a fresh install, premiere defaulted to:
Input - 2 ch 32 bit 44.1kHz
Output - 2 ch 32 bit 48 kHz

Setting input to "No input" resolved the playback issue with output set to the above 32bit-48kHz setting.

Matching input and output to:
2 ch 24 bit 48 kHz

Resolved the playback issue as well.

Again, seems that premiere sets the microphone input to an incorrect value that the system isn't capable of and causes a stuttering playback issue.

Since 24bit-48kHz is the tv/film standard for what is considered high-quality audio, please default Premiere to those settings.
