A question about the split feature in V6

hi; i need to split out several sections (individual shows) from a recording of several shows played back to back. I tried the split feature and i noticed that the start of each resulting "split" sections starts into the show by several seconds. As a test, i found a smpte time code video 1 hour long (@29.97fps). I loaded the sample and set the scene cut points at 20:00:00 and 40:00:00 and then split the file to get a 20 minute file. the resulting file shows as 20:00 under window information . when i load the resulting file into VRD the smpte code on the first frame is showing 20:25:08 and the end is 40:00:00. VLC wont run the file and windows movie maker shows the file as unplayable. If i do a "quick stream fix" on the 20 minute file, it comes back with a length of 19:34:22 (this is also displayed now in the windows length as well. i looked for any kind of padding and i don't see anything turned on. What am i doing wrong? Thanks for you help - update edited for my mess up of seconds vs minutes

I messed up the scale. the sample with the smpte code is 1 hour long not 1 minute long. where i say seconds it should be minutes. Sorry about the confusion. i updated the inital post to reflect the correct time scale. The video i'm using to test is 30 frames per second.

Use beta build 810 and if you still have the problem send the log file to support and we can take a look at what's going on.

i'll try to get some time tonight to try it on my system so i can use the latest beta build. can you point me to an example of supplying the log file ( how to zero it out, turn it on , find it after the activityis logged and upload it ) ? Thanks

The log functions you are asking about are all available from the TVSuite help menu.

OK from home. i downloaded the latest beta (6.60.6.810) and installed it. I ran a quick stream fix on the 1 hr long original file ( no errors or frames removed). in cut mode i set the start at 00:20:00:00 and the end point at 00:40:00:00. The individual frames have the actual smpte code displayed as 00:20:00:00 and 00:40:00:00. pressed add selection, then save video, then from the drop down of the save button , picked save with split scenes ( i kow i only have one "scene" selected but i get the same shorter segments whether i have one scene or more than one. The end result is a file listed under windows as 00:20:00 and under videoredo, the start of the file is 00:00:00:00 and the end is 00:19:34:22. The very first displayed frames has 00:20:25:08 in it. The last frame has 00:40:00:00 displayed. the log is attached.

The log file doesn't show any cuts at all, are you sure it's from the same day you did the test? Also, on the Tools>Options>General page, make sure the diagnostic setting is "medium".

Also, easiest way to send us the log file is to upload it directly to us via the Help menu.

Thanks.

Hi. I changed the location of the log file just before i loaded and "cut" the sample smpte file so the data in the log shouold reflect that activity. there was only the one file in the new directory and and it had the correct time and date. will try again tonight and send results. Thanks for your help.

Didn't see the log file. Can you try uploading again? How large is the log file?

hi, it's small. i uploaded it with videoredo app using the title of this thread and my email. i erased the file before i ran videoredo so the file should only have the specific single operation ("scene" from 00:20:00:00 to 00:40:00:00). the log file is on my home system. i will resend it again and upload it here as well tonight when i get home. i'm also going to try the cut mode ( which is what i normally use to trim the ends of recorded files off - only just now using scene mode to strip out several sections of a very large file ) and see if the cut points are correct in trim mode vs scene mode. i've used VRD in "cut mode" for years without any issue so i assume it has to do with "scene mode". Thanks for your help.

didn't get a chance to redo the send this weekend. Since the problem exists in the beta version at home and the demo version at work, i did the same cut again at work with the current demo version ( 1 day left on demo ) . i changed the log file path and restarted VRD so that the log should only show today's work. I reloaded and ran the same sequence twice, so there should be two "set" of single "scene" saves from 00:20:00:00 to 00:40:00:00. when i check the output files, the first frame has the smpte code 00:20:25:08. Thanks gain for your help with this.

I see the problem, it has to do with the mp4 output. If you try saving as mkv or ts, it should work better. Another option would be to disable the MOOV atom to front on the profile advance options page.

Can you upload the original source to us: tc_29.97fps_df_colon_60min-QSF.mp4? When the upload is complete send an email to support so that we know it's there.

Hi thanks for ckecking it. This is just a sample file that had smpte code in the frames so i could see how much was missing. I had the problem initially with a mp4 file created from a HDPVR2 recording the output of a DVR. I split out 6 or 7 sequential recordings (back to back seperated by a single frame) and saw the issue. The sample file i found was to big to upload when i generated the intial question. Here is a link to the the location that i got the example file from https://www.mediacollege.com/downloads/video/timecode/ . Its the 7th file from the top - right hand side "tc_29.97fps_df_colon_60min". i ran a quick stream fix on it ( to be sure it was "clean" for VRD) before i tested with it and then added the "-QSF" t the file name. it's very low res but very usfull when checking frame accuracy. if you can't find it, let me know and i'll try to upload it again but it did say it was to big to attach.

i tried saving as a TS and that worked fine. All the file i get out of my SageTv system are TS so i'm used to working with them ( and they can be converted back to mp4 for my Embry server. I'll tryed the upload link but it wants a ticket or thread number. is it 37150 ? thats whats on the end of the link to this thread. i'll upload with thread reference number 37150 and see what happens :)

Good. Just send an email when the upload is complete and we will create a ticket number and be able to test your uploaded file.

ok it says "Your files have been uploaded to the folder '37150'. Please send an email to support@videoredo.com and alert them of the successful upload. " so i sent an email, so you should have the reference file. Please note that this happens with other MP4 files coming from a HDPVR2.
