Hold off on this.

I've been testing some more, and it appears to happen sometimes, and not other times. I will play with this some more and try to figure out the pattern, if any. Bit rate? Size of file? Number of clips? What I fear is that it only happens with large files (3GB+), which would be difficult to send you. Maybe I can narrow down the variables.

Thanks.

Does it have any bug fixes?

I still say that it should NOT take 47 minutes to save a 9-minute MPEP-2 clip.

If I first convert the MPG file to DiVX/AVI, then it takes only about 2 minutes to save the same clip. When working with AVI files, I love the product. When working with MPG files (with index), Splittere is unusable. When working without an index, it saves the wrong clips and/or duplicate clips.

The original file is NTSC DVD-ready video, recorded by a Hauppage card. My computer is an AMD-64, 3GHz.

As I said above, I think the slowness bug is related to use of the index file. When I decline to use an index, the "Save Media File" command works quite fast.

BUT there is a different bug when the index file is not used. Last night I started with a 30-minute MPG video. I marked about 4 sections of commercials (maybe 10 minutes) to be removed. I saved the Media file. It grew from 30 to 36 minutes. None of the commercials was removed. One six-minute section (with both keep and throw away parts) was repeated.

And one more test:

I cancelled so that there would be NO index. I CUT three sections. I saved the media file. Again, it only took 3 minutes.

One more interesting thing: The resulting file is LARGER (2,755,253 KB) than the original (2,343,336 KB). My video player says it is 1:14 long (instead of 1:00).

I made different tests, based on my own guess.

First, I made a 1-hour clip (2.4 GB). (This time I made it CBR, not VBR, but I don't think that is the problem.)

I cut three commercials out, and saved the media file. It was taking "forever," so I cancelled.

I reopened the file, using the same index file. I made NO cuts, just saved the media file. It took "forever."

I reopened the file, but forced Splitter to re-index. I made NO cuts and saved the media file. Again, "forever."

I then deleted the index file and reopened the MPEG. As it started to re-index, I cancelled. The index file disappeared. THEN I saved the media file (NO cuts).

This time it only took only 3 minutes to save all 2.4 GB!

I think, therefore, that the slowness is related to the index.

Another thing: Scanning through the file (right-arrow key) takes longer and longer - slows down - as you go further along in the video. Perhaps there's a memory leak -- or possibly the algorithm for scanning starts at the beginning every time.

I think there's a problem with the index.

It did not take long for me either.

I think the problem is when editing large files - one or two hours - with large indexes.

I am now uploading a 2-minute clip (80,412,672 bytes). I made the file tonight. It is typical output from the Hauppage and has not been modified in any way. It will take at least another 2 hours for the upload to complete.

Another test:

I started with a two-hour MPG capture of the Grammy Wards last night. It took about 40 minutes to convert to MPEG-4/AVI, 10 minutes to slice-and-dice the AVI, and about 1 minute to save the commecial-free hour.

But when I split it up in the origfinal MPG form, it took 3 hours and 20 minutes to save 61 minutes of video. On a 3GHZ dual core AMD. Strange!

The original file was 4.5 GB. The output file was 2.2 GB. I have Async-DSL and it would lie up my connection (350Kb/s upload) for at least a day to FTP it to you.

If you wish, I can send you a SAMPLE of the MPG that my Hauppage WinTV-HRV 1800 is producing, before editing or touching in any way. Maybe that would be useful to you to look at. How many minutes to you need? (5 minutes = 200 MB).

Good news: The bug(s) where Splitter would fail to complete the tasks, or would freeze, appear to be fixed (one test). But it is still very slow.

I record copies of certain American (NTSC) TV shows and send them to a friend who is on a long trip to Uruguay. I record them in MPEG-2 PS with a Hauppage tuner. But I want them smaller, with commercials removed. I have been converting them to MPEG-4 AVI first, then using Splitter to remove the commercials.

This morning, it took about 10 minutes to find and mark the 14 commercial breaks in the AVI conversion of a 90-minute TV program (3.5 GB). Then it took only 1 MINUTE to save the trimmed AVI file.

As an experiment I used the new Splitter mark the same commercials in the original MPG file. It took 133 minutes to save the trimmed file. Splitter completed the job, but took a very long time to save. I don't know if this is necessary because it is MPG. I worry that some kind of transcoding is going on. I hope not.

I will continue to convert to MPEG-4 AVI first, then trim, for my friend's regular TV shows. I only need to split the orginal MPG files in cases where I want to archive the material without conversion. Splitter works, and I suppose I can live with the slowness if I only do this occasionally. But I hope some day you will find out why it takes so long.

Thank you for the update. I will be happy to take advantage of the new features.

Sorry, but I have been off the forum for a few weeks, and I hadn't noticed the update until today.

In the meantime, I have been splitting avi/MPEG4 files. MM Video Splitter is much slicker and easier than AVI Trimmer. It takes only 5-10 minutes to go through, mark and remove the commercials from an hour or two of TV recording, especially when the splitter program is enlarged to full screen. AVI Trimmer can do the job, but Splitrter is so much more of a pleasure to use.

I will install the update later and try again with some MPG files.

I tried the scenario in Example 1 again, but using a different input video that was recorded at a high bitrate of 6400 kbps.

50 minutes later, Video Splitter was frozen at 29% and had produced only 5 minutes of output video.

Therefore, I wonder if it has trouble with the high (6400) bitrate. Also, I wonder if it has trouble with US-standard NTSC interlaced video, even though it was originally encoded as a DVD program stream (720x480). These are just suggestions to think about.

My Hauppage card can only produce DVD, VCD, or SVCD, and all of it is 59.95 fields/sec interlaced video. I don't have to use 6400 kbps, but even with 3000 kbps input video this is slow.

I have to move on to other tasks now, but I will watch this forum to see if you come up with any ideas.

More info (according to G-Spot):

Example 1 was recorded with a video bitrate of 6400 kb/s
Examples 2 and 3 were recorded with a video bitrate of 3000 kb/s

(G-Spot says:) DVD-ready (720x480) MPEG-2 Program Stream 29.95 fps, system bitrate 6075 kb/s VBR, audio MP3 384 kb/s CBR. Generated by Hauppage TV tuner card.

Example 1. One input file was 4,983,696 KB (1 hour, 35 minutes). I tried several times, asking for 5 cuts to eliminate all except approximately 42 minutes. Splitter was unable to create more than 14 minutes (724 KB) of output before freezing. It took three hours to do this.

Example 2. Input file was 1,640,808 KB (1 hour 1 minute). I asked for an 8-minute (8:02) clip output. After 22 minutes, Splitter stopped at 99%. After waiting a few more minutes I shut the program down. Output file seems okay except for last frame or two.

Example 3. Input file was 1,641,192 KB (1 hour 1 minute). I asked for a 1-minute 35 second (1:35) clip output. After 11 minutes, Splitter stopped at 99%. After waiting a few more minutes I shut the program down. Output file seems okay except for last frame or two.

I am continuing to investigate.

Can anyone explain why it should take 45 minutes for Video Splitter to split out and save 7 minutes of MPEG-2 without re-encoding? This is a 3GHz dual core CPU. This is distressing and disappointing. I have used the free AVI splitter and I don't remember it taking so long.

It would take much less time to re-encode the video, but I want to avoid that.
