  1. Anamorphic Stretch

    Definitely get the anamorphic lens for your GoPro.  I have one for my GoPro and 2 for my iPhone/Samsung.  For the phones I have both the blue and golden coating.  Unfortunately, I have only found the blue for the GoPro.  I prefer the golden glares to the blue.  I'm really hooked on the wide screen movies and stills with the anamorphic lens.  The trick is to remember to desqueeze the images if your recording software does not save the desqueezed format.  Next we'll have to play with setting up slideshows in the letterbox formatting.

    My Skyreat 1.33X anamorphic lens for the GoPro has arrived but I have not tested. I hope to test soon.

    Thanks,

    I have updated 4:3 and added two more aspect ratios for NTSC and PAL format videos. Not sure how useful it will be for images but I think it sometimes helps videos.

    I use it to convert old 4:3 DVDs to 16:9 and add a slight amount of sharpen to the video. You could always make changes to the style zoom values.

    I think the original SuperView was designed to use the full sensor aspect ratio (4:3) instead of cropping to 16:9 and losing pixels.

    Playing with aspect ratio conversion. Instead of a linear X zoom it uses 10 image crops with 5 different X zoom values. I am planning on purchasing an anamorphic lens for my gopro and I wanted to test converting aspect ratios using image crop feature in PTE. GoPro has a SuperView feature that does something like this inside the camera.

    Probably not a style that is useful for most people unless you want your 4:3 media stretched to 16:9 instead of cropped.

  8. Cut Facility in Trim Video

    in Suggestions for Next Versions

    Posted

    Trim works in PTE..., but if you trim after adding the video to the show PTE as the main object it does not update the slide duration to the new duration of the trimmed video. I then have to go into slide options and manually change the duration. There is probably some automatic method that will do since it does not seem to bother anyone else.

  10. Camcorder Re-visited.

    in Equipment & Software

    Posted

    Hi Rosy,

    That is a very small camcorder. Not much larger than an action camera.  Sony makes very good image sensors. I remember using VHS-C and 8mm tape camcorders from 30+ years ago

    My GA400 action camera arrived yesterday. I hope to compare video quality/stabilization to the GP10 on my next bike ride.

  11. GoPro Image Stabilization Question

    in Equipment & Software

    Posted

    Hi Rosy,

    No. I didn't shave my arms. :)

    I only waited until HD was processed before posting to the forum. YT processes SD, the HD, then 4K. I checked and 4K is available now, but you might have to select it using the gear icon, quality setting. The other reason is the overcast sky is a diffused light source, with low contrast, and not many shadows. 

    Running out of cameras so I bought another budget action camera for my helmet to place in upper left corner of video.:) $90 and it's supposed to have 6 axis EIS. At first I was going to buy the GA320 but the GA400 video quality and EIS has improved.

  12. GoPro Image Stabilization Question

    Testing under bike seat camera. Another typical overcast day. The bumpy road on last section of video is scheduled to be resurfaced (notice spray paint on underground utilities) after environmental impact reports/coastal permits are approved.

    I find the GoPro attachment system challenging. It relies on compression to apply friction to a smooth plastic surface. The problem is if you have a plastic arm attached to the camera it can act as a lever and rotate the camera when hitting bumps in the road. Poor design. The only solution I can think of is to glue the plastic so it can not rotate. Also when the Yi camera is mounted upside down (beneath the bike seat) it does not sense the orientation so the date stamp should not be used. The Yi image stabilization does seem to be working at 1080/60 or it might just be the leverage suspension seat post.

  20. GoPro Image Stabilization Question

    Testing continues. I thought the Yi supported image stabilization at 4K but I was wrong. I will need to reshoot video at 1080p instead of 4K. The GoPro 10 continues to amaze me in video quality. I am impressed with the stabilization and dynamic range while heading into the sun with shadows from the trees. There is some curvature due to the wide angle lens that could be corrected by either shooting linear or shooting native sensor 4:3 AR and applying ReelSteady that corrects for wide angle lens distortion and crops to 16:9.

    Nice morning for a bike ride. Clear sky and cool weather.

  23. GoPro Image Stabilization Question

    HI Rosy,

    I was thinking maybe cloud cover but where we live it hardly ever changes in summer. Overcast in the mornings, sometimes clearing up if there is enough wind in the afternoons. Our average summer temperature near the Pacific ocean is usually less than 70F/21C. If you want higher temperatures you have to travel inland a few miles to a higher elevation above the reflective cloud cover.

    I will try to make a proper 2 camera comparison in the near future so the same amount of light is on both cameras. Looking forward to viewing your video.

    Thanks,
    Tom

  24. GoPro Image Stabilization Question

    Short video. Still learning about GoPro editing. Unfortunately due to operator error (me) my Yi camera did not record when dual mounted with the GoPro so I used a previous Yi video from a few days before in the same area (notice the white truck in the upper left change). Also the cameras need to be tilted up higher. The GoPro records in HEVC at 45 Mbps and splits videos into 4 GB segments. The Yi records H.264 45 Mbps but not limited to 4 GB file size.  Both cameras were set to 4K 24 fps. I think there are advantages to capturing at 24 fps like more light on the sensor and fewer frames to stabilize. The 4K quality out of the GoPro camera viewed on a 4K monitor is amazing. I re-encoded the video 2 times (GoPro player trim and PTE mask) and then uploaded to YT so there is some loss of detail in the video.

    The hypersmooth gyro stabilization does a very good job. The fine grain in the road is easier to see on the GoPro and the colors more saturated. I might do another video comparing GyroFlow, ReelSteady, FinalCut Pro, and Davinci Resolve stabilization software when I have time. I should also test the wide angle max lens mod for the GoPro.
