First, I'm fairly new to PP and have been using it for about 6 months but have been doing editing for years. I do curation of stock footage though and have done probably 30-40 clips and several 20 minutes YouTube videos in PP so far and haven't had this problem before. I feel like I'm such a newbie that I'm missing something that will be obvious to everyone else, however, in my searching I cannot find anything on the forums that seems to match this exactly. So here's hoping someone can set me straight.
As I said, I do stock footage. I normally grab a section of video that has multiple clips that I will be exporting and dump it into PP, do my color editing, and then hack it into clips that I will then export individually. Usually there are 2-3 clips to export per sequence. This has worked numerous times. This time however, I have a slightly larger clip than usual and after hacking it into 11 pieces, I started marking the clip selection and then exporting. Usually my marker isn't on the first frame so I don't notice anything odd when exporting. It's when I go to upload into my stock system that I see the first frame is black or even worse, the first frame of the clip is the last frame of the previous clip!
Exact method to duplicate issue:
1. Create project setting media files to a separate folder for easy deletion.
2. Import 240fps footage into project.3. Do color editing.
4. Using Razor Tool, cut sequence into clips, ripple delete extraneous clips.
5. Reduce speed on most clips to 12.5% (30fps).
6. Click clip to highlight, right-click marker bar and select "Mark Selection".
7. Click to "go to in" to see first frame is correct.
8. Export->Media (Ctrl+M) and see that first frame is now the last frame from previous clip.
9. If exported, the resulting footage will contain that bad frame at the beginning.
See screen shot:
My initial solution is that I have to make each clip a sub-sequence and then export the sub-sequence itself. This is an extra step that seems unnecessary considering this process has worked in the past.
- I am using PP CC 2019 v13.0.2 (build 38).
- The footage is in 240fps from a GoPro - Normally I work with 60fps footage.
- I am creating slo-mo at 30fps of most of the clips.
- If I put the marker on the first frame and then export the clip, in the preview it will show either the black frame or the frame of the last clip.
I've already tried deleting the media/preview files.
I saw something where someone was having issues with random black frames (not my issue) and they were told to set the sequence frame rate before editing. I'll admit that I haven't tried this yet as it wasn't exactly my issue and I didn't want to have to start over on this sequence since I've got about 4 hours in it. (I know I know...)
All I can see is the cti in the export settings is not on the same frame as in the timeline.
I thought this too, but you don't adjust that until you get to Export settings, correct? By then the issue is already there. I've tried changing it to match (I usually make sure it matches the correct FPS) and then exporting assuming it would fix it, but it doesn't.
I just ran the update to go to v13.0.03. This didn't change anything....
Can you post a screen shot of your sequence settings?
Is the 240fps source material imported as a 240fps clip?
5. Reduce speed on most clips to 12.5% (30fps).
How are you doing this?
Here you go.
Yes, source is a 240fps clip as shown below.
To change the speed:
I right-click the clip and select "Speed/Duration". Here's a screenshot:
Note: Since I'm doing stock, I delete the audio track completely.
And your sequence setting are?
Oh! sorry, I misunderstood... here:
Since you said this though, I got to thinking that maybe I should be setting the timebase here to what I expect to use for an FPS? I was under the impression that this should match the source. But I just hit up YouTube and saw someone recommending that it match the FPS of the clips I'll be editing.
The issue I had with this clip is that some of these clips are 30fps, and some are 60fps... Would I need to create separate sequences for each or at least know that I'll have to make a sub-sequence so I can export correctly?
1) I had no idea that Premiere would create a sequence with a timebase of 239.71 fps. Thought the upper limit was 60fps. Learn something new everyday.
2) If it were me - since you seem to be using sources with a variety of frame rates - I would create a sequence with the frame rate set to the frame rate I wanted to export in.
Then I would interpret the frame rate of the 240fps footage to that frame rate using Clip > Modify > Interpret Footage to that same frame rate ( the clip will now play in slow motion).
You can try creating a new sequence with the preset frame rate, then copy and paste the selected footage from your existing sequence into the new sequence and adjust the speed of the clips as needed - and see if that gives you the results you expect.
Thank you! You've given me some ideas to try. You have no idea how hard I searched for answers and I'm a tech guy with pro Google skills! LOL
I'm suspicious that you're right on this. I'll report back if I figure anything out!
You could start small and just make a test sequence with a couple of clips to verify the workflow works for you.
Hey have solved this problem ? I have been facing the same issue, it's very annoying.
Hey I'm still having the same issue. Premiere adds a single black frame at the begining of the exported video UNLESS you're at 00:00:00:00 in the timeline. The only way to "solve" this is to set your in point at the 2nd frame of your video, so it will export adding the previous frame to that, but this is really unproffessional. DO SOMETHING, ADOBE.
I am guessing the vfr is the culprit.
this is still an issue. no vfr on my timeline
