ProVideoCoalition Fight of the File Formats! PNGs or EXRs
Quite interesting, honestly I have never used EXR’s but I also don’t render to image sequence, I just use PNG’s for single images with alpha, but might need to rethink that.

Stability. Stability seems to be the thing most people complain about with Premiere Pro. I see all the time people complaining about it crashing.
AVID of course is going to have more stability if you do it’s normal workflow of importing footage, because you are compressing into an AVID format and of course that is going to be more stable, AMA of course, using external formats in AVID was not every going to be as stable.
To keep Premiere Pro stable I try to go for less compression, and pick a format and stick with that. Most of my deliveries are ProRES HQ, and if that is the case I want my footage to be be ProRES because it is going to be less compressed than many other highly compressed formats, especially formats like H.264. This wouldn’t apply if I was using a RAW format like ProRES RAW or Blackmagic RAW, which I would use with Proxy’s to speed thing up (though I would use ProRES Proxy and not H.264 Proxys).
So before import, I like to recompress my heavily compressed footage to ProRES HQ (or straight ProRES if that is the delivery spec). Yes this of course takes more time, but I have found that the stability that it gives me means that I save time on the back end, so the up front time is certainly worth it. And I use Media Encoder to it instead of using Ingest in Premiere Pro.
With Ingest you can Transcode, create Proxies, Copy or Copy with Proxies, and it is a great workflow when it works, but I have had bad crashes that have screwed things up and not finish the import or transcode process, so I tend to do transcodes myself before I import them. And yes this means I can’t start working right away, but I think the lost time up front is saved at the end when you don’t have any export issues.
I will talk about the Proxy workflow in another post, but I tend to do that in the program, but let it do it on it’s own, not while continuing to work because of crashing issues I have had. Best to let the machine go overnight, and if you can check it in remotely all the better.
And my compression issues extend beyond just you video files.
Since my early days of editing on Final Cut Pro 4-7, there have been issues with JPG images. Sometimes they are fine, and sometimes they can stop an entire project from opening, and it can happen randomly after working fine. Bad things happen with JPG images so I do not import JPG images into my projects.
Before using a JPEG I convert it to another format. Now I have seen people complain about PNG images causing problems in project, though I haven’t had that problem. I tend to convert to PNG, though the less compressed the better. And if you want to go even better you can go TIFF files, but they can end up being absolutely huge.
To convert images in a batch I use the $39.95 GraphicConverter from Lemkesoft.
I use the Convert And Modify command to convert my images from JPGS.
Setting Convert on the let, and PNG as the format (or TIFF if you would like). The folder with footage to covert is in the middle, and you select hte ones you want to convert, and the to folder is on the right, and you press start selected function.
I feel the same about Audio files, heavily compressed audio files like MP3 or M4A I convert to WAV files using Adobe Media Encoder.
And yes this is all in the “Assistant Editor Stage” before editing gets started. And the net result has been that Premiere Pro has been very stable for me. Sure sometimes I have issues, but since dealing with highly compressed footage, stills and audio before a project the program runs much more stable for me.
Honestly if you think about it, it is like using Premiere Pro more like AVID. You think of it as importing the footage to an AVID codec. And then everything is the same, and so will just run better.
And I often get A & B cameras that are different cameras, and thus different formats. Think about the computer having to uncompress different kinds of formats at once. Of course it is going to do better if everything is all one format.
And more compression means processing power, so the less compressed things are the less processing power you are using, and that can help with stability.
Everything you can do to make the whole thing run easier will mean less crashes and things working better.
