Stop crashes and stutter: right-size your media for reliable, silky-smooth playback.
Many entry-level media players and smart TVs advertise “4K,” but the operating system only guarantees 4K in their native streaming apps (Netflix, Prime, etc.). Third-party apps (like ours) often don’t get the same hardware-accelerated decoders, memory budgets, or bitrate allowances.
When you upload 4K images and high-bitrate 4K video, the device must decode, scale, and render massive frames. That spikes CPU/GPU, memory, and I/O, which leads to stutter, dropped frames, or app crashes.
Optimizing media to the actual pixels shown on the canvas and to a sane bitrate keeps playback smooth, lowers bandwidth/storage, and makes your content look sharper (ironically, oversized assets often look worse after on-device downscaling).
In the editor, click on the image → click Crop Image → set the target size (Width and height) → Save.

Use HandBrake to downscale and tame bitrate.

When you truly need 4K: keep bitrate modest (e.g., 12–20 Mbps H.264 or H.265), but expect some entry-level devices to struggle with playback.
