Brian and Steve, thank you for replying so quickly! Here’s a little more information.
My computer is a Lenovo ThinkPad E550. I never bought it intending to make videos. I only ever use a computer (laptop) for Word documents, email, copying CDs into iTunes, making photo books with Blurb dot com, and resizing photos for posting on the internet. Of course I check email, shop at Amazon, check Facebook, the usual. But making videos was not on my mind when I bought this computer two years ago.
It’s running on Windows 8 (I heard of so many problems from friends who went to 10, so unless it automatically updated, I’m still on 8). I don’t know about computer specs so well but this one has Intel Core i5-5200U CPU @ 2.2 GHz. Honestly, this computer does slow down at times and can be annoying for someone like me who wants to get the job done well and quickly, as my computer time is usually after 10:30pm after I come home from work and I have to get up at 6 am. So, I sometimes go for days on five hour’s sleep because I have so much I want to do when I get home.
About Shotcut, my video and still photo files come from a Canon 6D. The stills are resized to 1000 pixels wide, which is what I do for Flickr, too. The audio comes from the camera (using a RODE mic) and from music files either from my iTunes library (Apple lossless from CD) or downloads from friends who are musicians. I have made some shorter videos combining music and stills or one 3:40 video of videos of nature and a friend’s acoustic guitar track. Though there were delays and unresponsive times while making these videos, I never had a problem with exporting the final video. Granted, the longest video was about 6 minutes with one audio track and one video track.
I had one thought. The first instructional video I watched for Shotcut said that each video had to be encoded and put in the playlist. Then each video was cut and edited and arranged in order in the playlist before the whole playlist was exported as one video. I did my first trial video this way, following the instructions as I went. This way, I clipped and stitched five short videos together to make a 3-minute video. Again, there were delays and small glitches, but the exporting was completed after 16 minutes. But the next video I watched showed how to edit in the timeline, which was much easier and how I had imagined it. I soon found out how to add additional video and audio tracks, isolate audio tracks to put with different video tracks (e.g. my guitar playing with a video of albums and music memorabilia), add text and inserts, and so on. And so I went for the gold, making a 24-minute video that combined all of these: short videos, music audio tracks, stills inserts, text, etc. But I can’t export it!
I uninstalled Shotcut and then installed the January version (I had the December one). It’s the 32-bit version as my computer can’t work with the 64-bit one, so it tells me. I tried one more time to export the video. It looked positive because previously the export time was given between 1:49:00 and 2:06:00 but this time it said about 49 minutes. But then the app crashed again…
I hope this helps somewhat. If you need some specifics, please ask me. Any advice would help. Should I encode my short videos first, arrange them in the playlist and then export them from the playlist? I like working from the timeline, though. The actual process is very easy.
